It was good to see Marvin Compper making his bow in front of the Celtic support during the week, and it will be interesting to see how he shapes up and fits into this Celtic team.

He is obviously a defender of great experience, and he has played at a really high level both in his native Germany, and in Italy too with Fiorentina.

It’s maybe a wee bit surprising to see Celtic signing a 32-year-old, but he has been awarded a two-and-a-half year contract by Brendan Rodgers, so his signing may not be as short-term as it may appear.

It’s just a little bit disappointing that he is cup-tied for the Europa League, but Celtic have obviously decided that the positive attributes he has can contribute to the team in such a way that it outweighs that one negative.

If he can play half as well as he can speak languages, then Celtic will have a player on their hands.

The big thing they have bought with him though is that experience at the back, and that was vital. It was an area that definitely needed to be addressed, as the lack of it at the heart of the defence has been exposed on a few occasions this season.

I don’t mean that to be a bad reflection on the players who are already there, who I do rate, but I think that the need for more numbers there was proven by the fact that Nir Bitton had to step in there on occasion this term.

He didn’t let himself down, he did well for someone that isn’t a recognised defender, but Brendan obviously knew that that wasn’t a long-term solution, and has acted accordingly.

After being so short of numbers in that area previously though, the Celtic manager now has a balancing act on his hands, because neither of the two centre-backs there currently there will be happy at dropping out. Dedryck Boyata has World Cup ambitions with Belgium, and Jozo Simunovic was probably the better performer there until the game against Hearts.

And at 32, Compper won't have come to Scotland to sit on the bench. I'll be interested to see who will be the one to make way for him.
